Download blazing fast and uniquely safer tools for a modern image workflow. Note: We aren't labeling Imageflow as 'stable' until enough people have tested it. Please help us test and provide feedback! Also, please, please, please send us 'challenging' images and tasks.
Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools. This approach leads to a significant file size gain relative to lossless approaches at the expense of a relatively modest decrease in image quality (see example images below). Historical benchmarks with the files included in Cédric Louvrier's PNG Test Corpus versus other commonly used PNG optimization software are available in BENCHMARKS.md.
IJG is an informal group that writes and distributes a widely used free library for JPEG image compression. JPEG is designed for compressing either full-color or gray-scale images
of natural, real-world scenes.
JBIG2 encodes bi-level (1 bpp) images using a number of clever tricks to get better compression than G4. It can compress multipage documents. It generates JBIG2 files, or fragments for embedding in PDFs.

imgp is a command line image resizer and rotator for JPEG and PNG images. It can resize (or thumbnail) and rotate thousands of images in a go, at lightning speed, while saving significantly on storage. Powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation (and more), imgp is a very flexible utility with well-documented easy to use options.
TensorFlow Implementation for learned compression of images using Generative Adversarial Networks. The method was developed by Agustsson et. al. in Generative Adversarial Networks for Extreme Learned Image Compression. The proposed idea is very interesting and their approach is well-described. Training is conducted with batch size 1 and reconstructed samples / tensorboard summaries will be periodically written every certain number of steps (default is 128). Checkpoints are saved every 10 epochs.
ImgBot crawls all your image files in GitHub and submits pull requests after applying a lossless compression. This will make the file size go down, but leave the dimensions and quality just as good. ImgBot supports optional configuration through a .imgbotconfig json file. This is not a required step to using ImgBot and is only for more advanced scenarios. This file should be placed in the root of the repository and set to your liking.
ImgSVD is a Shiny application for image compression via singular value decomposition (SVD). This application is inspired by Yihui Xie's comment in Yixuan Qiu's article on image compression via singular value decomposition with the R package rARPACK. Currently, ImgSVD supports input images in JPEG or PNG format.
Phew is an open-source FLIF image viewer and QuickLook plugin for macOS. The Free Lossless Image Format or FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms of compression ratio.
